Description

The present invention relates to compositions for treating fabric articles, especially articles of clothing, linens and drapery, wherein the compositions provide improved cleaning of soils from and/or care of and/or treatment of fabric articles, especially while providing superior garment care for articles sensitive to water as compared to conventional fabric article treating compositions.

BACKGROUND OF THE INVENTION

For the cleaning of fabric articles consumers currently have the choice of conventional laundry cleaning or dry cleaning.

Conventional laundry cleaning is carried out with relatively large amounts of water, typically in a washing machine at the consumer's home, or in a dedicated place such as a coin laundry. Although washing machines and laundry detergents have become quite sophisticated, the conventional laundry process still exposes the fabric articles to a risk of dye transfer and shrinkage. Significant portions of fabric articles used by consumers are not suitable for cleaning in a conventional laundry process. Even fabric articles that are considered “washing machine safe” frequently come out of the laundry process badly wrinkled and require ironing.

Dry cleaning processes rely on non-aqueous solvents for cleaning. By avoiding water these processes minimize the risk of shrinkage and wrinkling; however, cleaning of soils, particularly water-based and alcohol-based soils, is very limited with these processes. Typically, the dry-cleaner removes such soils by hand prior to the dry-cleaning process. These methods are complex, requiring a wide range of compositions to address the variety of stains encountered, very labor intensive and often result in some localized damage to the treated article.

Accordingly there is an unmet need, in commercial laundry, in dry-cleaning and in the home, for fabric article treating compositions, which simultaneously provide acceptable cleaning of across a variety of soils while remaining safe for a wide range of fabric articles.

SUMMARY OF THE INVENTION

The present invention provides compositions which exhibit improved cleaning of soils from and/or care of and/or treatment of fabric articles. These benefits may be delivered to the fabric article treated by the compositions of the present invention while maintaining excellent fabric care properties.

DETAILED DESCRIPTION OF THE INVENTIONDefinitions

The term “fabric article” used herein is intended to mean any article that is customarily cleaned in a conventional laundry process or in a dry cleaning process. As such, the term encompasses articles of clothing, linens, drapery, and clothing accessories. The term also encompasses other items made in whole or in part of fabric, such as tote bags, furniture covers, tarpaulins and the like.

The term “lipophilic fluid” used herein is intended to mean any nonaqueous fluid capable of removing sebum, as described in more detail herein below.

The term “fabric article treating composition” used herein is intended to mean any lipophilic fluid-containing composition containing cleaning and/or care additives that comes into direct contact with fabric articles to be cleaned. It should be understood that the term “fabric article treating composition” encompasses uses other than cleaning, such as conditioning and sizing. Furthermore, optional cleaning adjuncts such as additional surfactants other than those surfactants described above, bleaches, and the like may be added to the “fabric article treating composition”. That is, cleaning adjuncts may be optionally combined with the lipophilic fluid. These optional cleaning adjuncts are described in more detail hereinbelow. Such cleaning adjuncts may be present in the fabric article treating compositions of the present invention at a level of from about 0.01% to about 10% by weight of the fabric article treating composition.

The term “soil” means any undesirable substance on a fabric article that is desired to be removed. By the terms “water-based” or “hydrophilic” soils is meant that the soil comprised water at the time it first came in contact with the fabric article, or the soil retains a significant portion of water on the fabric article. Examples of water-based soils include, but are not limited to, beverages, many food soils, water soluble dyes, bodily fluids such as sweat, urine or blood, outdoor soils such as grass stains and mud.

The term “capable of suspending water in a lipophilic fluid” means that a material is able to suspend, solvate and/or emulsify water, in a way that the water remains visibly suspended, solvated or emulsified when left undisturbed for a period of at least five minutes after initial mixing of the components. In some examples of compositions in accordance with the present invention, the compositions may be colloidal in nature and/or appear milky. In other examples of compositions in accordance with the present invention, the compositions may be transparent.

The term “insoluble in a lipohilic fluid” means that when added to a lipophilic fluid, a material physically separates from the lipophilic fluid (i.e. settle-out, flocculate, float) within 5 minutes after addition, whereas a material that is “soluble in a lipophilic fluid” does not physically separate from the lipophilic fluid within 5 minutes after addition.

The term “consumable detergent composition” means any detersive composition, that when combined with a discrete lipophilic fluid, results in a fabric article treating composition according to the present invention.

The term “processing aid” refers to any material that renders the consumable detergent composition more suitable for formulation, stability, and/or dilution with a lipophilic fluid to form a fabric article treating composition in accordance with the present invention.

The term “mixing” as used herein means combining two or more materials (i.e., more specifically a discrete lipophilic fluid and a detergent composition in accordance with the present invention) in such a way that a homogeneous mixture or stable dispersion or suspension is formed. Suitable mixing processes are known in the art. Nonlimiting examples of suitable mixing processes include vortex mixing processes and static mixing processes.

Compositions of the Present Invention

The present invention provides compositions which exhibit improved cleaning of soils (i.e., removal and/or reduction of soils) from and/or care of and/or treatment of fabric articles. These benefits may be delivered to the fabric article treated by the compositions of the present invention while maintaining excellent fabric care properties. while maintaining excellent fabric care properties.

Lipophilic Fluid

The lipophilic fluid herein is one having a liquid phase present under operating conditions of a fabric article treating appliance, in other words, during treatment of a fabric article in accordance with the present invention. In general such a lipophilic fluid can be fully liquid at ambient temperature and pressure, can be an easily melted solid, e.g., one which becomes liquid at temperatures in the range from about 0 deg. C. to about 60 deg. C., or can comprise a mixture of liquid and vapor phases at ambient temperatures and pressures, e.g., at 25 deg. C. and 1 atm. pressure. Thus, the lipophilic fluid is not a compressible gas such as carbon dioxide.

It is preferred that the lipophilic fluids herein be nonflammable or have relatively high flash points and/or low VOC (volatile organic compound) characteristics, these terms having their conventional meanings as used in the dry cleaning industry, to equal or, preferably, exceed the characteristics of known conventional dry cleaning fluids.

In general, lipophilic fluids herein are required to be fluids capable of at least partially dissolving sebum or body soil as defined in the test hereinafter. Mixtures of lipophilic fluid are also suitable, and provided that the requirements of the Lipophilic Fluid Test, as described below, are met, the lipophilic fluid can include any fraction of dry-cleaning solvents, especially newer types including fluorinated solvents, or perfluorinated amines. Some perfluorinated amines such as perfluorotributylamines while unsuitable for use as lipophilic fluid may be present as one of many possible adjuncts present in the lipophilic fluid-containing composition.

Other suitable lipophilic fluids include, but are not limited to, diol solvent systems e.g., higher diols such as C6- or C8- or higher diols, organosilicone solvents including both cyclic and acyclic types, and the like, and mixtures thereof.

A preferred group of nonaqueous lipophilic fluids suitable for incorporation as a major component of the compositions of the present invention include low-volatility nonfluorinated organics, silicones, especially those other than amino functional silicones, and mixtures thereof. Low volatility nonfluorinated organics include for example OLEAN® and other polyol esters, or certain relatively nonvolatile biodegradable mid-chain branched petroleum fractions.

Another preferred group of nonaqueous lipophilic fluids suitable for incorporation as a major component of the compositions of the present invention include, but are not limited to, glycol ethers, for example propylene glycol methyl ether, propylene glycol n-propyl ether, propylene glycol t-butyl ether, propylene glycol n-butyl ether, dipropylene glycol methyl ether, dipropylene glycol n-propyl ether, dipropylene glycol t-butyl ether, dipropylene glycol n-butyl ether, tripropylene glycol methyl ether, tripropylene glycol n-propyl ether, tripropylene glycol t-butyl ether, tripropylene glycol n-butyl ether. Suitable silicones for use as a major component, e.g., more than 50%, of the composition include cyclopentasiloxanes, sometimes termed “D5”, and/or linear analogs having approximately similar volatility, optionally complemented by other compatible silicones. Suitable silicones are well known in the literature, see, for example, Kirk Othmer's Encyclopedia of Chemical Technology, and are available from a number of commercial sources, including General Electric, Toshiba Silicone, Bayer, and Dow Coming. Other suitable lipophilic fluids are commercially available from Procter & Gamble or from Dow Chemical and other suppliers.

Qualification of Lipophilic Fluid and Lipophilic Fluid Test (LF Test)

Any nonaqueous fluid that is both capable of meeting known requirements for a dry-cleaning fluid (e.g, flash point etc.) and is capable of at least partially dissolving sebum, as indicated by the test method described below, is suitable as a lipophilic fluid herein. As a general guideline, perfluorobutylamine (Fluorinert FC-43®) on its own (with or without adjuncts) is a reference material which by definition is unsuitable as a lipophilic fluid for use herein (it is essentially a nonsolvent) while cyclopentasiloxanes have suitable sebum-dissolving properties and dissolves sebum.

The following is the method for investigating and qualifying other materials, e.g., other low-viscosity, free-flowing silicones, for use as the lipophilic fluid. The method uses commercially available Crisco® canola oil, oleic acid (95% pure, available from Sigma Aldrich Co.) and squalene (99% pure, available from J. T. Baker) as model soils for sebum. The test materials should be substantially anhydrous and free from any added adjuncts, or other materials during evaluation.

Prepare three vials, each vial will contain one type of lipophilic soil. Place 1.0 g of canola oil in the first; in a second vial place 1.0 g of the oleic acid (95%), and in a third and final vial place 1.0 g of the squalene (99.9%). To each vial add 1 g of the fluid to be tested for lipophilicity. Separately mix at room temperature and pressure each vial containing the lipophilic soil and the fluid to be tested for 20 seconds on a standard vortex mixer at maximum setting. Place vials on the bench and allow to settle for 15 minutes at room temperature and pressure. If, upon standing, a clear single phase is formed in any of the vials containing lipophilic soils, then the nonaqueous fluid qualifies as suitable for use as a “lipophilic fluid” in accordance with the present invention. However, if two or more separate layers are formed in all three vials, then the amount of nonaqueous fluid dissolved in the oil phase will need to be further determined before rejecting or accepting the nonaqueous fluid as qualified.

In such a case, with a syringe, carefully extract a 200-microliter sample from each layer in each vial. The syringe-extracted layer samples are placed in GC auto sampler vials and subjected to conventional GC analysis after determining the retention time of calibration samples of each of the three models soils and the fluid being tested. If more than 1% of the test fluid by GC, preferably greater, is found to be present in any one of the layers which consists of the oleic acid, canola oil or squalene layer, then the test fluid is also qualified for use as a lipophilic fluid. If needed, the method can be further calibrated using heptacosafluorotributylamine, i.e., Fluorinert FC-43 (fail) and cyclopentasiloxane (pass). A suitable GC is a Hewlett Packard Gas Chromatograph HP5890 Series II equipped with a split/splitless injector and FID. A suitable column used in determining the amount of lipophilic fluid present is a J&W Scientific capillary column DB-1HT, 30 meter, 0.25mm id, 0.1 um film thickness cat# 1221131. The GC is suitably operated under the following conditions:

Carrier Gas: Hydrogen

Column Head Pressure: 9 psi

Flows: Column Flow @˜1.5 ml/min.

Split Vent @˜250-500 ml/min.

Septum Purge @1 ml/min.

Injection: HP 7673 Autosampler, 10 ul syringe, 1 ul injection

Injector Temperature: 350° C.

Detector Temperature: 380° C.

Oven Temperature Program: initial 60° C. hold 1 min.

rate 25° C./min.

final 380° C. hold 30 min.

Preferred lipophilic fluids suitable for use herein can further be qualified for use on the basis of having an excellent garment care profile. Garment care profile testing is well known in the art and involves testing a fluid to be qualified using a wide range of garment or fabric article components, including fabrics, threads and elastics used in seams, etc., and a range of buttons. Preferred lipophilic fluids for use herein have an excellent garment care profile, for example they have a good shrinkage and/or fabric puckering profile and do not appreciably damage plastic buttons. Certain materials which in sebum removal qualify for use as lipophilic fluids, for example ethyl lactate, can be quite objectionable in their tendency to dissolve buttons, and if such a material is to be used in the compositions of the present invention, it will be formulated with water and/or other solvents such that the overall mix is not substantially damaging to buttons. Other lipophilic fluids, D5, for example, meet the garment care requirements quite admirably. Some suitable lipophilic fluids may be found in granted U.S. Pat. Nos. 5,865,852; 5,942,007; 6,042,617; 6,042,618; 6,056,789; 6,059,845; and 6,063,135, which are incorporated herein by reference.

Lipophilic fluids can include linear and cyclic polysiloxanes, hydrocarbons and chlorinated hydrocarbons, with the exception of PERC which is explicitly not covered by the lipophilic fluid definition as used herein. (Specifically call out DF2000 and PERC). More preferred are the linear and cyclic polysiloxanes and hydrocarbons of the glycol ether, acetate ester, lactate ester families. Preferred lipophilic fluids include cyclic siloxanes having a boiling point at 760 mm Hg. of below about 250° C. Specifically preferred cyclic siloxanes for use in this invention are octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane. Preferably, the cyclic siloxane comprises decamethylcyclopentasiloxane (D5, pentamer) and is substantially free of octamethylcyclotetrasiloxane (tetramer) and dodecamethylcyclohexasiloxane (hexamer).

However, it should be understood that useful cyclic siloxane mixtures might contain, in addition to the preferred cyclic siloxanes, minor amounts of other cyclic siloxanes including octamethylcyclotetrasiloxane and hexamethylcyclotrisiloxane or higher cyclics such as tetradecamethylcycloheptasiloxane. Generally the amount of these other cyclic siloxanes in useful cyclic siloxane mixtures will be less than about 10 percent based on the total weight of the mixture. The industry standard for cyclic siloxane mixtures is that such mixtures comprise less than about 1% by weight of the mixture of octamethylcyclotetrasiloxane.

Accordingly, the lipophilic fluid of the present invention preferably comprises more than about 50%, more preferably more than about 75%, even more preferably at least about 90%, most preferably at least about 95% by weight of the lipophilic fluid of decamethylcyclopentasiloxane. Alternatively, the lipophilic fluid may comprise siloxanes which are a mixture of cyclic siloxanes having more than about 50%, preferably more than about 75%, more preferably at least about 90%, most preferably at least about 95% up to about 100% by weight of the mixture of decamethylcyclopentasiloxane and less than about 10%, preferably less than about 5%, more preferably less than about 2%, even more preferably less than about 1%, most preferably less than about 0.5% to about 0% by weight of the mixture of octamethylcyclotetrasiloxane and/or dodecamethylcyclohexasiloxane.

The level of lipophilic fluid, when present in the fabric article treating compositions according to the present invention, is preferably from about 70% to about 99.99%, more preferably from about 90% to about 99.9%, and even more preferably from about 95% to about 99.8% by weight of the fabric article treating composition.

Cleaning Adjuncts

The compositions of the present invention may optionally further comprise one or more cleaning adjuncts. The optional cleaning adjuncts can vary widely and can be used at widely ranging levels. For example, detersive enzymes such as proteases, amylases, cellulases, lipases and the like as well as bleach catalysts including the macrocyclic types having manganese or similar transition metals all useful in laundry and cleaning products can be used herein at very low, or less commonly, higher levels. Cleaning adjuncts that are catalytic, for example enzymes, can be used in “forward” or “reverse” modes, a discovery independently useful from the fabric treating methods of the present invention. For example, a lipolase or other hydrolase may be used, optionally in the presence of alcohols as cleaning adjuncts, to convert fatty acids to esters, thereby increasing their solubility in the lipohilic fluid. This is a “reverse” operation, in contrast with the normal use of this hydrolase in water to convert a less water-soluble fatty ester to a more water-soluble material. In any event, any cleaning adjunct must be suitable for use in combination with a lipophilic fluid in accordance with the present invention.

Perfumes and perfumery ingredients useful in the compositions of the present invention comprise a wide variety of natural and synthetic chemical ingredients, including, but not limited to, aldehydes, ketones, esters, and the like.

Finished perfumes may comprise extremely complex mixtures of such ingredients. Pro-perfumes are also useful in the present invention. Such materials are those precursors or mixtures thereof capable of chemically reacting, e.g., by hydrolysis, to release a perfume, and are described in patents and/or published patent applications to Procter and Gamble, Firmenich, Givaudan and others.

Bleaches, especially oxygen bleaches, are another type of cleaning adjunct suitable for use in the compositions of the present invention. This is especially the case for the activated and catalyzed forms with such bleach activators as nonanoyloxybenzenesulfonate and/or any of its linear or branched higher or lower homologs, and/or tetraacetylethylenediamine and/or any of its derivatives or derivatives of phthaloylimidoperoxycaproic acid (PAP) or other imido- or amido-substituted bleach activators including the lactam types, or more generally any mixture of hydrophilic and/or hydrophobic bleach activators (especially acyl derivatives including those of the C6-C16 substituted oxybenzenesulfonates).

The finishing polymers can be natural, or synthetic, and can act by forming a film, and/or by providing adhesive properties to adhere the finishing polymers to the fabrics. By way of example, the compositions of the present invention can optionally use film-forming and/or adhesive polymer to impart shape retention to fabric, particularly clothing. By “adhesive” it is meant that when applied as a solution or a dispersion to a fiber surface and dried, the polymer can attach to the surface.
